AUTHORITIES insist that Casuarina residents' health is not at risk from thick dust that has been blowing into their homes for several months from the town centre construction site.

A series of meetings has been held in the last week, involving the developers, representatives from the State Government and Tweed Shire Council and homeowners, about the dust from the old sand-mining site blanketing the area and fears that it has elevated radiation readings.

A Department of Planning spokesman said an infringement notice in relation to air quality had been issued and they, together with the council, would continue to "closely monitor compliance on the site to ensure strict approval conditions are being met".

Mayor Barry Longland and Tweed State MP Geoff Provest say they are satisfied there are no health issues apart from the discomfort caused by the dust.

But both expressed disappointment the builders hadn't acted earlier to alleviate the problem.

Mr Provest called for more truly independent analysis of the site.

I am sick of the sand that is coming into our pools, landing on our cars, covering my floors, my curtains, our computers.

Resident Megan Mckay Brodhurst-hill said the grit and dust problem was like "beach camping in your own home".
